IMPROVEMENT IN APPARATUS FOR SUPPLYING HY DROCARBON OILS T 0 BUILDINGS.

Specification forming part of Letters Patent N0. 196,360, dated October23, 1877; application filed November 12, 1875.

To all whom it may concern:

Be it known that I, JOHN S. HULL, of Ointion.

cinnati, in the county of Hamilton and State of Ohio, have invented anImproved Apparatus for Supplying Hydrocarbon Oils to Buildings forHeating and Illuminating Purposes; and I do'hereby declare that thefollowing is a full and exact description thereof, reference being hadto the accompanying drawing, making part of this specification, andrepresenting an inside view of a building provided with the apparatus,parts of which are shown in vertical section.

The object of my invention is to furnish a practical, convenient,economical, and safe means of supplying hydrocarbon oils to the variousparts of a building, for various heating and illuminating purposes, thefluid being supplied to the burners under sufficient pressure forproducing light, and to produce a flowing and intensely-hot flame.- Theforce employed to raise the oil to the various parts of the building andproduce the pressure at the burners is that of compressed air upon theoil in the containing vessel or tank. The oils are conducted to thedifferent parts of the building by means of pipes.

Special features of improvement will be hereinafter specified.

-In the drawing, A, B, and 0 indicate the first, second, and thirdstories of a building provided with my apparatus. Any greater number ofstories may be similarly provided.

' The tank or reservoir D, which receives the supply of the hydrocarbonoils, and from which they are distributed to all parts of the building,is located outside of, and safely isolated from, the building.

A further-precaution against accident by fire is provided by locating inthe tank a safety filling-tube, a, made of finely-perforated sheetmetal, reaching from the top to the bottom thereof inside, to preventthe possibility of communicating flame to the oil inside of the tank orreservoir. A drawing-tube, I), also reaches-nearly to the bottom side,being perforated at the lower end.

In combination with the tank or reservoir D, I employ another reservoiror close vessel, E, for containing a supply of compressed air for theoil-tank. This air-tank is preferably placed in the building in aconvenient posi- It is provided with a condensing airpump, J, either asa permanent attachment or separate, as shown in the drawing, andcommiuiicating with the air-reservoir by a pipe or tube, 0. Occasionallythis pump is operated to keep up the requisite pressure in theairreservoir, and consequently in the oil-tank, which communicates withthe air-reservoir by a pipe or tube, 11, the pressure being indicated bya gage, e. requisite to be supplied, since only enough needs to be addedto fill the space emptied by the consumption of the oil. Stop-valves fand g, respectively, are employed to prevent the return of the air fromthe air-reservoir to the pump, and from the oil-tank to theairreservoir.

From the oil-tank D a supply-pipe, F, extends, drawing from. the same,near the bottom thereof, and provided with a globe or stop valve, n.This supply-pipe may first extend to the requisite height to supply allthe stories of the building, and from this pipe branches G H Iextend tothe several stories. Stopvalves 2' i i are located in the pipe F, atvarious heights, to cut off any of the stories when desired.

In many cases I prefer to have supplementary oil-tanks K L on a levelwith the several upper stories, preferably situated on platforms outsideof the'building. They may be much smaller than the main tank D, andcontain only a present supply each for its own story. By means of suchsupplementary tanks, the great pressure of the oil in the pipes in highbuildings is relieved, and the pressure equalized in the :difierentstories. They also increase the tankcapacity, or enable a smaller maintank. to be used. They are connected with the main supply-pipe F bybranch pipes, and through the said supply -pipe they are filled from themain tank by the pressure of the air in the latter. They may beseparately connected with the branch supply-pipe, as between the tank Kand pipe H, from which the main. supply-pipe E may be cut off by astop-valve, j.

There may also be an additional air-reservoir, M, as shown, ormore, ifdesired, one for each additional oil-tank. Thus the tank M is Not alarge amount of air is '3 represent self-gasifying heating-burners,

' and V a double shifting or revolving fire-pot supplied with compressedair from the main reservoir E through a pipe or tube, 7:, and from thereservoir a pipe, 1, extends to the tank K, and another pipe, m, fromthe same reservoir to thetank L. All these communications are capable ofbeing closed by stop-valves. Above the upper pneumatiepressure tank, orthe upper-story supplypipe, I also locate a static pressure tank, Nwhich may be of moderate size. It'comnumicates with the supply-pipes,and is filled, as are the other supplementary tanks, from the main tank.It serves to keep up a supply of oil in' the service-pipes while fillingthe other tanks, or in case of repairs being done to the tanks orair-reservoir. The oil therein may be ordinarily cut oif from the pipesby a stop-valve, being thus held as a reserve supply.

The uses of this apparatus for heating and lighting are exemplified inthe drawing, which also shows the method of applying the same forspecial purposes. Thus, 0 O O O in the several stories representgasifying-burners, for lighting the rooms connected directly with thesupply-pipes. A steam-heating apparatus, P, for heating the building isrepresented, a being a steam-generator, through which a heating-flue, 0,extends to apply the heat from a self-gasifying pressure-burner, 19, oneor more, connected with the supply-pipe G, there being also asteamsuperheating coil and pipe, q, in the flue. The steam-pipe isrepresented as continuing upward to a steam-radiator, Q, in the storyabove, and it may continue to as many radiators as desired. Theremaining heating devices represented in the drawing are specialapplications for the various processes of a canning establishment, towhich this apparatus is peculiarly adapted. Thus, It

connected with the supply-pipes, and S S tinners fire-pots combinedtherewith, for heating soldering-irons for seaming, floating, andcapping preserve-cans. As many of these burners and fire-pots may beused as there is room for in the building or as may be desired for thepurpose. T represents a similar burner,

to heat soldering'irons for tipping preserve cans. The two fire-potscomposing the device are mounted on a supporting-shaft, so located thatfirst one fire-pot can be brought before the burner and then the other,so that one solderingiron can be in process of heating while theoperator is using the other. Finally,

aprocessing chamber or chest, W,is employed for processing the filledcans. This is supplied with steam inside, introduced therein through apipe, 9", finely perforated, and connected with the steam-pipe of thesteam-heating apparatus. In connection with the processingchest W,another self-gasifyiug' burner, X, connected with the supply-pipe, isemployed for use in processing.

What I claim as my invention, and desire .to secure by Letters Patent,is-

1. The combination, in a building, of an oiltank, I), a separateair-reservoir, E, for supplying compressed air to said tank, and pipes FG H I, for conducting the oil from the tank to different parts of thebuilding, for heating and illuminating purposes, substantially as heremspecified.

2. The combination of an oil-tank, D, situated outside of the buildingwhich it supplies with oil, and a separate compressed-air reservoir, E,connected therewith by a suitable pipe or passage, (2, substantially asand for the purpose herein specified.

3. One or more elevated pneumatic-pressure auxiliary oil-tanks, K L, incombination with the main oil-tank D and connecting-pipe F,substantially as and for the purpose herein specified.

4. In combination witha pneumatic-pressure oil-tank, 1), andsupply-pipes F G H I, an elevated static-pressure auxiliary oil-tank, N,substantially as and for the purpose herein specilied.

Specification signed by me this 3d day of May, 1875.
